NEW YORK - PepsiCo is once again learning the risks of celebrity partnerships after an ad for Mountain Dew was criticized for portraying racial stereotypes and making light of violence toward women.

The soda and snack food company said it immediately pulled the 60-second spot after learning that people found it was offensive. The ad was part of a series developed by African-American rapper Tyler, The Creator, and depicted a battered white woman on crutches being urged to identify a suspect out of a lineup of black men.

A goat character known as Felicia is included in the lineup and makes threatening comments to the woman, such as "Ya better not snitch on a playa" and "Keep ya mouth shut."

The woman eventually screams "I can't do this, no no no!" and runs away. The word "do" is in apparent reference to the soft drink's "Dew It" slogan.

Mountain Dew, known for its neon color and high caffeine content, is generally marketed to younger men and sometimes attempts to have edgier ads. But the controversy over its latest spot illustrates the fine line that companies must walk when trying to be hip.

In fact, Mountain Dew also was criticized recently because of its endorsement deal with Lil Wayne, whose rap lyrics compared a rough sex act to the tortuous death of Emmett Till, a black teen who was murdered in 1955 for allegedly whistling at a white woman. Last month, Reebok also ended its relationship with Rick Ross after he rapped about giving a woman a drug to have his way with her.

Laura Ries, president of Ries & Ries, a marketing firm based in Atlanta, said companies that want the "street cred" of a celebrity may end up losing control of the message they want to convey.

If PepsiCo had created an ad for Mountain Dew, for example, she said it might not have been considered edgy or cool. But by handing over control to a celebrity, she said the company ran the risk of having an ad that wasn't appropriate.

PepsiCo Inc., based in Purchase, N.Y., said it understood how the ad could be offensive.
